To all whom tmay/ 'co/acera: y' e f e Be it known that l'. Fans W; Tanni:7` a citizen oi" the Liiitedv States and a .esident of Chicago Heights` in the county oi Cooky and State of Illinoisf-have invented certain new and useful improvements in I Farin Tractors, ot' which the following is a speci-' fication. p

My invention relates generally to tractors and particularly to iiarm tra'ctorsfior'haul-A ling 'farming implements 'oit'l various descrip-r tions.

vehicle for steering the same whichvisoperable by steering rods disposed at the iront and rear ot the vehicle, such rods being capable ot movement to an,inoperative'position so that one or the other canv actuate the steering mechanism independently of the other. It is also a purpose 'of my' inventiony to` provide 'a driving mechanism toi." the rear wheelsiot thetractor which is constructed to drive the wheels from two positions, suchk `wheels being 'reversible so as to permit the hauling of cultivatorsof various sizes.'

"I vwilldee'scribe one form of farm tractor embodying 'my invention 'and will then point outythe novel features in claims.

In the accompanying` drawings:

It is a purpose of my invention'to provide a tractor 'having means at the front oi the 'n the bolsters Figure 71' is a view showing in side eleva-x' ytion one torment' farm tractor -embodynig particularly to FigureslA and 2,10 designates a chassis upon'which is arrangeda pairoi" bolsters B and B forresiliently supporting a -vehicle body V thereon.'y As shown in Figure 2 the shownkin F igures`559` andlO, each bolster B "and comprises reyersely -fdispos'ed U-shaped bars 18 and 19 supported upon v`verticallydisposed rodsQO-QO which are chassis@v comprises side rails i I andarear rail 17. kAs f secured within the upper bars 18. The rods l 20-2-0 have' a sliding" iit within suitable 'openings formed inthe 'sideM rrails 15,` and interposed between the rails"- 15 and they bars 1S are coiled springs 21 which normally bias upwardly so as to resiliently support the vehicle body V. It will be understood that the vertical portion of the bars 18 einbracethe sides oi" the vehicle body and thus rhold the .saine in proper position upon the "chassis i i The chassis C is supported by' front' wheels 1V and rear wheels 1V', the latter ot which constitute the driving wheels. As shown to advantage 1n Figure 4, each'fo'f` the driving wheels is mountedupon a stub axle S. The f stub axles S are'supported 'in brackets Gr, each of which ispivo'tally supported 'at its upper end between. a pair of semi'circular plates P, secured kto the opposite sides ofk ythe rails 15.

As shown/iii Figure '11, eachy bracket G comprises a single length of matcrial which is bii'urcated Aatits lower end rto form clampingI jaws through which extends a bolt E28 for actuating they jaws to eiiect the clamping of the stub lshaft S. The

To effect this4 vertical adiust-` opening 26 formed in thebracket` ,andni thereby/locks the bracket in adjusted posi tion within the ra dius of the openings. "The f construction of the plates and the manner in which the locking of the bracl'ets G is effected is clearly shown inFigure 13.

As shown in Figure 3, the driving'wheels y WV lare disposed upon theouter sides of the chassis C, and -when in this position, which positionl willterm the ekpanded7 imstoitl the stub "axles extend inwardly from the Wheels with their inner ends projecting from the confronting sides oi 'the brackets G. ln order to lreinforce the stub axles S, l provide a tubular sleeve 27 which receives the confronting` ends ot the aides S and S and is rigidly connected thereto by bolts 2S, thus formino` :i rigid connection between the two axles.Y rihe Wheels Vil are adapted to be placed upon the inner sides ot the brackets (i. as illustrated in Figure 4. This position. of the driving' Wheels I term the contracted position. ln order to reverse the Wheels 'from the expanded` to the contracted positionthe axles S and S are removed from the brackets by loosening` the` bolts 23. whereupon they are again inserted into the brackets 'from the inner sides thereof. n

To driverthe Wheels lill when incontracted or expanded position, l provide one side yof each Wheel with a relativelylarge `fear 29 sok and 29,'respectively. which is adapted to mesh with a pair oit relatively7 small gears `30 vand 31. and 30% and-3l, respectively.

The gears 30l and 3l are fixed Vto a shattll, While' the gears 30a and` 31a are vtiXed to a shaft H. such shafts .il and H bcingoperativelv connected at their inner ends 'by means of a suitable form. oi differential inclosed in a casino` D.

It VWill be understood .panded or contracted position. -posef of vreversibly mounting` the, driving that the transmission.y driving shaft. and differential have not been shown asthey may be oit any suitalole .term anddo not constitute any. part ot the present invention.

Frein this arrangement it will be seen that theshaiits irl and H drive the Wheels lV through the gears 9.9. 29-, 30, etc. When the Wheels Wf are in the expanded position. the gears 29 and Q9 mesh ivitliutho gears 3() and 30a. but when such Wheels are in the contracted position theiiI `gears mesh With the gears 3l and 31a. lt will thus he seenthat a positive driving' .means is provided for the driving ivheels'when in. ei:- The purvvheels isto accommodatek the tractor to large or Asmall cultivators. For example.

`should-a single'ronT eultivator be attached to the.v rear end of the tractor the driif'c-ivhecls Wf are placed in the contracted position. When the tractor is hauling; a cultivator vvhichis capable of Working; tvvo or more rows. the drive Wheels are placed in the ei:- panded position. i yEsteri-infr 110W toflfiggures l and f2. the WheelslV. 'constitute thestcering wheels of the vehicle'. and in order to steer the vehicle from the front or rear thereoiQI provide the l.liolloxvinsr mechanism:

.\. designates the axles 'tor the Wheels Wliichpasshoivnto advantage in Figure 2,

are of L-shaped formation and are inclosed in casings The vertical portion ot each shaft A is suitably journaled in the chassis C and a beam which is disposed belovv the chassis, and wholly supported by the axle. Interposed between thebeain and the chassis C are coiled springs ffl-@Which surround the vertical portions o'l' the shaft A and serve to resiliently support the 'ton Ward end of the chassis upon the wheels WV. Fixed to the vertical portionsof the shaft A are Worm gears 3:39 `Which.as shown in Figures 6 and y7. are adapted to mesh with Worms 36 formed on the opposite endsioii a shaft 37. Fixed to the shaft Si' is a worin gear 38 which is adapted 'to he rotated in one direction or the other by means ot steering rods R and R which are toi-ined with terms 39 and 40. respectively,' as clearly shown in Figure S. The steering' rod 'R 85 extends upwardly into a proper position `in f relationto the operators seat on the body V, and. as Will be understood. is adapted toy be operated When the driver is at `the 'forward end of the vehicle. The steeringr rod R extends longitudinally ot the chassis C and projects from the rear end thereot. as clearly shown inFigure 2. so that the vehicle may be steered from the rear. As l have illustrated the steering' rods R and R` in' Fiserure 8. the worms 39 yand 40 mesh with the gear 38,l but it is to be understood that ivhen one or the other ot such steeringr rods is being used the remaining rod is disconnected from. the =efear 38. Tol this end, the steering` rods R and Rv are normally locked in operative position Withrelation to the 4fear 38 by means ot `collars K and K, respectively. rwhich are arranged upon oppo-y site sides of the dash otfthe vehicle body V and. the rear of the rail 17 oi the chassis, respectively. These collars K and K', are provided with set screws l1 and lila, respectively. vvhich serve to lock the collars in any desired position upon the steering` rod. Assuming that it is desired to steer the tractor through the medium ot the steering rod R.

it Willbe necessary to disconnectthe steeringr rod R Jfrom the Worm ,gear 38. To ei.-

r.ifect this end, the collars K.`disposed"upon opposite sides of the rail 17, are released bv their set screws so that the steering rod R can be moved rearwardly, thusmoving its worm. 40 clear ot the 4.crear 38. iIn this position ofthe steeringr rod R the ymanipulation of the Worm `ear 38'in no Way affects thek steeringr rodso that the Wheels :W may be moved to any desired position'independently ot the steering rod R. It' it is desired to steer the vehicle 'trom the rear, it vvill be 125 understood thatthe steering rod R is moved to the inactive position, in a manner similarly described in relation to the steering rod lit. ln the inactive position of? the steering rod7 the collars K or` Kk arelocked to 180 the rods in the position shoivn in the draW- ing, so that the rods may be rotated but can not move longitudinally.

Although l have herein. shown and de-y scribed only one form of tractor' embodying my invention, it is to be understood that various changes and inodiiications may be made Without departing from the spirit of the inif'ention and spirit and scope of the appended claims. 'i
